Description

液晶面板及其液晶配向方法、液晶显示器Liquid crystal panel and liquid crystal alignment method thereof, liquid crystal display 技术领域Technical field
本发明属于液晶显示技术领域，具体地讲，涉及一种液晶面板及其液晶配向方法、液晶显示器。The invention belongs to the technical field of liquid crystal display, and in particular to a liquid crystal panel, a liquid crystal alignment method thereof and a liquid crystal display.
背景技术Background technique
随着光电与半导体技术的演进，也带动了平板显示器(Flat Panel Display)的蓬勃发展，而在诸多平板显示器中，液晶显示器(Liquid Crystal Display，简称LCD)因具有高空间利用效率、低消耗功率、无辐射以及低电磁干扰等诸多优越特性，已被应用于生产生活的各个方面。With the evolution of optoelectronics and semiconductor technology, the flat panel display has also flourished. Among many flat panel displays, liquid crystal displays (LCDs) have high space utilization efficiency and low power consumption. Many advantages such as no radiation and low electromagnetic interference have been applied to all aspects of production and life.
液晶显示器通常为背光型液晶显示器，其包括相对设置的液晶面板和背光模块。液晶面板的工作原理是在两片平行的玻璃基板(即对盒的彩膜基板(CF基板)和阵列基板(Array基板))当中放置液晶分子，两片玻璃基板通过向液晶分子通电与否来控制液晶分子改变方向，从而将背光模组的光线折射出来产生影像。The liquid crystal display is usually a backlight type liquid crystal display including a liquid crystal panel and a backlight module which are oppositely disposed. The working principle of the liquid crystal panel is to place liquid crystal molecules in two parallel glass substrates (ie, a color filter substrate (CF substrate) and an array substrate (Array substrate)), and the two glass substrates are energized by liquid crystal molecules. Controlling the liquid crystal molecules to change direction, thereby refracting the light of the backlight module to produce an image.
目前主流的液晶面板的类型分为扭曲向列(Twisted Nematic，TN)或超扭曲向列(Super Twisted Nematic，STN)型、面内转换(In-Plane Switching，IPS)型、垂直配向(Vertical Alignment，VA)型以及边缘电场驱动(Fringe-field Switching)型。其中IPS模式是利用与基板面大致平行的电场驱动液晶分子沿基板面内转动以响应的模式，由于具有较大的可视角度以及响应速度快等优点，所以被用于各种TV显示用途当中。而FFS模式是通过同一平面内像素间电极产生边缘电场，使电极间以及电极正上方的液晶分子都能在平行于基板的平面方向发生旋转转换，从而提高液晶层的透光效率，以克服IPS模式的透光效率低的问题，在宽视角的前提下，实现了高的透光效率。At present, the types of mainstream liquid crystal panels are classified into Twisted Nematic (TN) or Super Twisted Nematic (STN) type, In-Plane Switching (IPS) type, and Vertical Alignment (Vertical Alignment). , VA) type and Fringe-field switching type. The IPS mode is a mode in which the liquid crystal molecules are driven to rotate in the plane of the substrate in response to an electric field substantially parallel to the substrate surface, and is used in various TV display applications due to the advantages of large viewing angle and fast response speed. . In the FFS mode, the fringe electric field is generated by the inter-pixel electrodes in the same plane, so that the liquid crystal molecules between the electrodes and directly above the electrodes can be rotated and converted in the plane direction parallel to the substrate, thereby improving the light transmission efficiency of the liquid crystal layer to overcome the IPS. The problem of low light transmission efficiency of the mode achieves high light transmission efficiency under the premise of wide viewing angle.
然而，在现有的IPS型和FFS型液晶面板的液晶配向过程中，液晶分子的预倾角无法达到0°，从而IPS型和FFS型液晶面板在暗态时出现漏光现象。 However, in the liquid crystal alignment process of the existing IPS type and FFS type liquid crystal panels, the pretilt angle of the liquid crystal molecules cannot reach 0°, so that the IPS type and the FFS type liquid crystal panel leak light in a dark state.
